Title: Optic refractive index measuring apparatus
Inventor: IWAMOTO MASAKATSU
IPC: A61B3/103
Filed: 1989-05-29
Abstract: PURPOSE:To eliminate an error of a measured value due to an optical axis deviation between an optical axis of a measuring optical system and an optical axis of an eye to be inspected by a method wherein an aperture is arranged at a position being almost conjugated with a cornea of the eye to be inspected pertaining to an eyepiece lens and has a stop hole small enough to let a luminous flux passing a point at which a measuring light receiving optical system optical axis crosses the cornea pass selectively thereon among reflected lights of a spot image on a retina. CONSTITUTION:Selected with an aperture 24 arranged at a position conjugated with a cornea E1 with respect to an eyepiece lens 22, a luminous flux alone near an optical axis of a receiving system is introduced into an imaging lens 27 passing through the aperture 24. When provided on a receiving system optical axis a2, the aperture 24 with a stop hole small enough allows a luminous flux very small alone passing a point at which a measuring optical system optical axis a2 crosses the cornea E1 among reflected lights of a spot image on a retina E2 to be extracted selectively on a sensor 29.

Title: Through-hole plating method of printed wiring board
Inventor: TOYOSHIMA TAKEHIRO
IPC: C25D7/00
Filed: 1990-05-25
Abstract: PURPOSE:To prevent such a trouble that plating is not deposited on the wall face of a through-hole from occurring by a method wherein the speed and the stroke of a plated object are specified, and a control scope of points required for the wettability of treatment solution to the plated object is cleared. CONSTITUTION:Provided that rho denotes the density (kg/m<2>) of treatment solution, CD is drag coefficient, V represents the oscillation speed (m/s), theta is a contact angle (degree) of treatment solution with the plated object, R denotes the diameter of a through-hole, and gamma represents a surface tension (N/m). A condition under which air bubbles are removed from a through-hole and treatment solution flows into it is given by a formula, V>(4 X gamma X (1-cos theta) mu CD<-1> Xrho<-1> X R<-1>)<1/2>. In the formula concerned, gamma, theta, CD, rho, and R are all measurable physical quantities, so that these are measured, whereby the range of a vibration speed of the plated object can be obtained from the formula. The amplitude of oscillation is set larger than the length of the through-hole of the plated object in an oscillation direction. By this setup, such a trouble that plating is not deposited in a through-hole can be prevented.

Title: Manual hang-up and hang-down device
Inventor: TAKAMORI SHIGERU
IPC: B66D5/16
Filed: 1987-05-30
Abstract: PURPOSE: To permit lifting of a load, utilizing force of both hands, by hanging the load from one side of a rope laid on a pulley, gripping the other side by an operator, and preventing the hanging load from dropping by a ratchet claw of a ratchet lever. CONSTITUTION: In lifting a load, when the free end of a rope 10 for hanging a load is pulled down, ratchet lever 3 is rotated counterclockwise, a ratchet claw 3a is separated from the rope, the checking action is released, and the rope 10 is rotated together with a pulley 2 counterclockwise to lift the load. Next, when the hands are separated from the rope 10, the lever 3 is rotated clockwise, the claw 3a strongly bites the rope 10 to generate the checking action, and therefore, the load is not freely dropped. When the load is lowered, a remote control cord 12 is pulled down. Since the checking action of the lever 3 is released during pulling, the load is freely dropped. If pulling-down of the cord 12 is released, the lever 3 generates the checking action by the weight of the load, and the rope 10 is stopped by the ratchet claw 3a.

Abstract: PROBLEM TO BE SOLVED: To provide an OTDR(optical time domain reflectometer) measuring device with a function to automatically correct the changes of reference voltage values. SOLUTION: A light coupler 3 joins and branches the waves of incident probe light and of rear-scattering light from an optical fiber of measurement. Each branch light is detected at light-receiving elements 6a and 6b and outputted as a detection current. A differential amplifier 8 compares the detection voltage outputted from a current-to-voltage converter 7 with the reference voltage on which a predetermined arithmetic is performed to a root-mean-square signal outputted from an adding circuit 11 at an arithmetic circuit 20 and which is converted to analog form at a digital-to-analog converter 21, and outputs a difference signal. The above-mentioned reference voltage is set on the basis of a root-mean-square signal in the state that rear-scattering light is not incident from the optical fiber of measurement.

IPC: G03B27/72
Filed: 1983-07-27
Abstract: PURPOSE:To obtain an excellent picture without deteriorating S/N by controlling a fluorescent lamp current through a light quantity detection output and detecting light quantity and a surrounding temperature so as to raise an alarm signal to the deficient light quantity at a high temperature. CONSTITUTION:Light of a fluorescent lamp 1 is formed on a CCD3 through a reflection mirror 12 and a lens 13. The CCD3 outputs a signal having a level in response to the amount of light reception, this output signal is fed to a peak hold circuit 10 through an amplifier 5 and peak level is held. The peak level is compared with a reference voltage V1 at a comparator 6, and when the peak level is larger than the V1, an output of a flip-flop 11 goes to an ''H'' level to reduce a tube current of the fluorescent lamp and when smaller, the output goes to an ''L'' level to increase the tube current. On the other hand, when the ambient temperature reaches a prescribed value or over, since the potential at a point P is lower than a reference potential V2, an output of a comparator 7 goes to ''H'' level and an alarm signal is outputted.

Filed: 1989-05-31
Abstract: PURPOSE:To easily control transmitted light by interposing a control mechanism which controls the light quantity of the transmitted light between a display body and a light source without controlling the light source itself in a backlight type display device. CONSTITUTION:The display device is constituted of the display body 3 which visually confirms display indices such as a display character and a graphic with the transmitted light and the light source 1 which emits the light transmitting the display body 3. A liquid crystal part 2 which controls the transmitted light by selectively energizing the split electrode in a liquid crystal cell is interposed between the display body 3 and the light source 1. When the split electrode is selectively energized in the liquid crystal 2, the selected part interrupts or transmits the light.

Abstract: PURPOSE:To make it possible to carry out emergency operation of an engine such as self-moving of a vehicle when a sensor for detecting a position of a fuel regulating member is troubled, by stopping operation of the engine once, and then designing to operate the engine without a signal from the sensor as desired. CONSTITUTION:When any troubles are generated in a servo control unit during operation of an engine 4, and the troubles are determined by a trouble determining unit 8, a switch 17 is turned off to stop the engine 4. At this time, an indicator 16 indicates generation of the troubles to permit a driver to immediately recognize the generation of the troubles and take necessary measures. Thereafter, when a switch 18 is turned on, the switch 17 is turned on by a switch control unit 15 to select a selector switch 12 to a dotted line. As a result, an open loop control data D6 instead of data D5 is supplied to a driving circuit 13 to carry out an emergency mode operation. Accordingly, a vehicle may be moved by itself to a safety place. Further, as such as emergency mode is indicated by the indicator 16, the driver can recognize an operation mode.
